effect in advertising various articles of commerce. Moving automatons attract the eye and attention of prospective purchasers in a manner which the ordinary stationary sign or display device of other character is incapable of doing and a more extensive use of automatons has heretofore not been attempted because of the expense involved in their installation and operation. and because of the large space which they occupy.

It is one of the principal objects of this vertising soda fountain drinks, or in fact drinks of any character, which is inexpensive to manufacture in'the firstinstance; which is small in size and adapted to 'be installed in a small space in a store or a display window; which may be automatically and continuously operated by means of electric power; and which requiresno connections other than 'a pair of electric wires for conducting the current from the electric mains to a motor.

One embodiment of theinvention' will be fully disclosed in the following description when taken in connection with" the accompanying drawings, in which:

Figure 1 is a front elevation of the device:

Figure 2 is a similar viewbut showing the automaton in a different position and parts thereof bein brokenaway to show the mechanism;

Figure 3 is a top view of the device Figure 4 is a section along the'line 4--,4 of Figure 3 to a larger scale part being broken away and showing certain of the parts in positions different fromithose which they occupy in Figure 3; Figure 5 is a horizontal sect-ionthrough a portion of the pump; and e Figure 6 is a vertical section'thr'ough the drinking glass held by the automaton Figure -7 is a plan view of a detail.

Theadvertising device comprises a flat wooden orcardboardfigure, indicated at 1.0, which may be that of ama-n, as illustrated, or; of awoman or child. To the right of the figure and indicated at 11 is a wood or cardboard structure representing the usual soda fountain, the rearedge of the member ,11 'beingsecured to a wall 12 in the rear of the, Figure .10. Mechanism for: operating the automaton is concealed behind this and behind the structure 11 representing the soda fountain, y In operation the. concealed mechanism vmoves the pivot arm l3 of the automaton so that the glass 14 which it holdsis carried from the soda dispensing spigot or faucet .15 toa position in frontof the Figure 10 and; directly; below, its mouth piece. In the last position mentioned the glass is emptied,

the-fluid therein :passing upwardly. through the glass tube 16, andthroughthe mouth of the automaton into asystem of piping by .means of which it is conducted back to the glass, to ,be again consumed by the 'autornaton, :i-In. other words, the automaton is caused to drink the same liquid repeatedly at regular intervals,although so far as the observer" in, -front of the device can detect, the'figure receives from the fountaina fresh glass of liquid each time the glass is placed beneaththe spigot.15.

The mechanism for moving the arm in this manner. and for causing the glass to be alternately'filled 'and emptied will now be described. Leading 'rearwardly, from the rubber mouth piece 17 of the automaton is a pipevl 8 which opens into a cylinder 19 containing a'sliding piston" and constituting a'pumpand a pipe 21 connects the pump cylinder 19- and a storage reservoir 20 lo- .catedbehind'the structure 11 ,-and elevated above thelevel ofthespigot 15. Nonreturn valves 22 'and'23' respectively are located at y the endsof the pipes 18 1,116.21 where they enter'the cylinder 19, and the function of these valves is toi'insure that the liquid passes through the pump system in one direction only, which is of course, from. the pump-to the storage reservoir 20as indicated :by 'the arrows. The piston of the pumpi-s fconnectedby a rod'24 tothe U shaped shaft 25,, on one end of which isv mounted the pulley 26, connected by means of a belt; 27- tothe small drive pulley of a mall electric motor,28;, Rotationpf the Cir nclined position an 7 as is adapted to tom-at arre t 70a ;-u1;e vv1 a 3-1 m f ,t

motor causes the,v pump to operateto withdraw, on its up stroke, the contents of the glass through the pipe 18 and to force the same, on its down stroke, through the pipe 21 into the storage reservoir 20. This pumping action although slow, takes place coni stantly, so that Whenever the'glass is brought into drinking position by the arm its liquid content is slowly drawn up the .tube lfi and is I forced innnediately afterwards into the storage reservoir, i p

The liquid entering the storage reservnir is held therein until the glass 1 l hasl'been placed underthe spigot15,f whereupon itis allowed to flow fronifthejreservoir into the glass, Themeans for controlling the floyv of id. W er byl' it s e ased;0n y a he.

As the top ofrtheu shaped member is above the level'ofthe liquid surface When in its vertical positiomnolliquid can flow frointhe reservoirlto the glass, but

M I turned 'to vert cal" POSltIOIll The ' arm: inith'e'l opposite direction; A spr ionf36 at has} descended to such an extent that the member 36 has engaged the arm 37 to force or cam the same out of its path. It is apparent therefore that as soon as the float 33 has descended a predetermined distance and'a predetermined amount of fluid has passed from the reservoir 20 to the glass,the

U shaped tube will be returned to vertical position, immediately cutting off the flow. This valve action occurs when the glasshas been filled, 'When the reservoir 20 has been refilled by the puinp, the float 33 is, of

cour se ,i in its uppermost position and the tube 30 may be again rotated to inclinedpo- For rotating the tub'e.30 to inclined position, a lever 3,3 pivotally mounted in the \vall,of stiucture 1 1 is provided, having a horizontal portion 38" outside of the Wall and ilitlie offthe glass lewd asecond 38 within the Wall and lylng, in the, pathof'the lower endrof rod tl etube, 30 to 'verti'c al position and to stop the flow of fluid at the same instant that the 'arinactuating mechanism is called into action to removetheglass, the lever 38 being simultaneously; and automatically returned to its original positio b the'rod 31. The arm 13' has at its inner or elbow end "a worm wheel 39 meshing ivith a wormfttl mounted uponthe end-of a shaft 4e1jsupported in the rear of the Figure 10 and having a pivoted'connection to ashaft42.

When the lever is in position as shown in Figure 4" the shaft 42 is drawn, against the pressure of the spring 46, so that the wheels 43 and 44 are in engagement and the arm 13 is in extended position. The lever 48 is held in such position until the float 29 has descended to its lower limit of travel by a pivoted supporting member 50 normally pressed by a leaf spring 51 toward the stem 34. When the float has approached its lower limit of travel the cam surface on the upper end of the stem 34 engages the lateral projecting shoulder. 50 near the lower end of the pivot member 50 and the latter is forced to the left (Figure 2) against the action of the leaf spring 51, and the upper end of themember 5O disengages the lever 48 which falls until it again rests upon the upper end of the stem 34. When the lever 48 falls the connecting cord '47 allows the spring 46 to shift the rod 42 so that the friction wheels 43 and 45 are in contact.

' so the flow or liquid might continue until the float chamber is drained, means is provided for automatically opening the tubeto the air at its highest point when itreturns to vertical position. This means comprises a valve 52 pivotally secured to tube 30 and having an aperture 53 and an arm 54, the valve being normally positioned as shown in full lines in Fig. 7 by a weak tension spring 55. As the tube 30 approaches vertical position the end of valve arm 54 strikes a projection 56 on wall 11 and the valve is rotated to the dotted line position (Fig. 7) in which position the aperture 53 is in register with an aperture 57 in tube 30 and air is admitted into the tube to break the suction. As the tube 30 swings downwardly from vertical position, spring 55 causes valve 52 to rotate to close the aperture 57.

This cycle of operations will be continued as long as the motor is supplied with current. It is not necessary in this device for any connection to be made to a large liquid tank or to a water supply system inasmuch as the same liquid is used indefinitely. While the device is neat and attractive in appearance it is not expensive to manufacture, the parts are simple in construction, easily accessible, and the mechanism is easy to re pair. Suitable advertising matter may be printed on the cardboard or wood figure or other structure and the device placed in a comparatively small space in a store'or dis play window.

It will be obvious that changes may be made in the form and arrangement of the parts of the invention, which is not limited to the embodiment described and illustrated.
